SOCKET AnnEAsE FOR TBANSLATING nEvIcEs.

Application filed January 12, 1926. Serial No. saw.

This invention relates to sockets and bases for translating devices, andparticularly to thoseadapted for use with replaceable trans- 3 latingdevices having a so-called valve I action.

The object of the invention generally is to provide an improvedconstruction and arrangement of arts which is eflicient, economical andrea ily manufactured.

More specifically an object of the invention is to provide a socket andbase whereby translating devices such as asymmetric cells of the drysurface-contact variet may be easily inserted and withdrawn rom elec- 18trical systems using the same without impairing its contact connectionstherewith or otherwise interfering with the operating characteristicsofthe devices.

Other objects of the invention will be in part be obvious and will inpart appear hereinafter.

The invention accordingly comprises the features of construction,combinations of elements, and arrangement of parts, which will beexemplified in, the constructions hereinafter set forth and the scope ofthe application of which will be indicated in the claims,

For a fuller understanding of the nature and objects of the inventionreference should be had to the following'detailed description taken inconnection wlth the accompanying drawing, in which:

Figure 1 is a view showing a side elevation of a typical translatingdevice having asymmetric cells of the dry surface-contact varietyprovided with a base in accordance with the invention;

Fig. 2 is a view showing in elevation a translating device of thecharacter specified removed r view being taken at right angles to thatof Fig. 1;

- Fig. 3 is a view, partly in section and partly in plan, arrangedtoshowthe adaptation of the base device so as to. fit the socket in accordancewith'the invention; and

Fig. 4 is a top plan view of the socket with the translating deviceremoved.

Referring now particularly to thedrawing, 10 denotes a translatingdevice, shown by way of example as having a plurality of asymmetriccouples 11 of the dry surface contact variet such as disclosed in thecopending application for Letters Patent of om its socket, the plane ofthe the United States'filed by Samuel Ruben on November 18, 1924, SerialNo. 750,939. The couples thus provided are arranged to have a so-calledvalve or rectifying action and are preferably disposed symmetrically oneach side of a central conducting plate 12; the nut and bolt, shownate-13, serving to retain the couples properly in place. The symmetricalarrangement here illustrated-is adapted to utilize both halves of thealternating current; butwhile the arrangement is convenient, it is by nomeans essential to the practice of the present invention. A

In this arrangement, conducting end plates 14 are applied to the devicewhich have the same polarity but is the opposite of that of plate 12.These end plates areconveniently extended as indicated at 15 and haveupset portions 16 which are adapted to support the device as a unit uponthe insulating disc 17, the latter serving as the base proper for therectifying unit here provided. The conducting portions 16 thus securedto the base 17 are adapted to be connected to one terminal of the directcurrent circuit, since they have the same polarity.

To this end the contacting portions 16 have extensions 18 which extendbeyond the base to engage with the socket in the manner hereinafterdescribed.

The insulating base, as indicated in-Figs. 1 and 2, is adapted to beremovably disposed in a socket 30, and when inserted, to a make thenecessary contacts with the conductorsof the electrical system to whichit is applied. The base 17 is accordingly provided with additionalcontact elements connected to the various portions of the rectifyingdevice. In ac cordance with this provision, thebase is shown in Fig. 2as havin three depending contact elements'2'1, 22 an 23, which projectthrough the base 17, but

' are cut short on the upper side. They may be made in tubular form orotherwise provided with countersunk openings as indicated at '24 (seeFig.- 3), as this feature facilitates the insertion of the conductors25, 26 and 27 g which are provided to make contact with the elements ofthe asymmetric couples 11. For example the conductors 25 '8.Ild. 27 aresecured respectively in contact elements 21 and 23 andareconnectedto'in- 'termediate points in the group of a metric coupleswhich are at o posite s des of the central plate 12, while t e conductor26, which leads-from the plate 12, makes contact with the middle contactelement 22,

A. rectifying unit provided with a base as shown at 17 in Fig. 2, isadapted to be removably supported in a socket which has conducting meansdisposed to engage in bayonet fashion with the projections 18. This isconveniently accomplished by the arrangement here shown, where aconducting collar 30 is mounted on an insulating plaque of othersuitable support 31. The conducting collar, thus provided, hasupstanding lugs 32 formed with slots on opposite sides into which theprojections 18 may be slid for bayonet engagement with theconductingcollar 30 by a partial rotation.

The collar 30 is arranged to be conduc tively connected with theconducting terminal clip 33 disposed on the underside of the insulatingplaque 31. It is adapted to provide a suitable terminal through whichthe direct current circuit is connected to the translating device. Inorder to provide similar terminals for the other circuit, connections,the insulating plaque 31 supports additional contact members, preferablyof the spring variety, which make suitable contact with the contactelements 21, 22 and 23. This may be conveniently accomplished withoutcutting away the whole of the insulating plaque 31 within the conductingcollar 30, thereby providing a strong and convenient arrangement.Accordingly the insulating plaque 31 has a perforation 35 centrallydisposed within the conducting collar'to accommodate the centrallydisposed contact element 22 projecting from the base. Disposed underthis perforation is a spring con* tact member 36 which has a terminalclip 37 adapted to serve as the other terminal of the direct currentcircuit. In like manner elongated perforations 38 are provided in theinsulating plaque on diametrically opposite sides of the centralperforation 35. These elongated perforations admit the insertion of thedepending contact elements 21 and 23 to make contact respectively withthe springcontact members 39 which have terminal clips 40 extending atopposite sides of the insulating plaque 31. are sufliciently elongatedto permit the inserted contact elements 21 and 23 to turn through an arcof suflicient magnitude to permit the partial rotation of the rectifierunit to a position where the projections 18 clear the lugs 32 so thatthe rectifying unit 10 may be withdrawn or replaced.

By this invention, it will be seen, that a rectifying or liketranslating device ma be arranged in convenient units on a base w ich isadapted to be removably inserted in a socket where it makes contact withthe conductors of circuits in an electrical system such as is employedin the rectification of.

The perforations 38 alternating currents. In such a system, for example,the clips 40 are adapted to serve as the alternating current inputterminals, while the clips 33 and 37 are adapted to serve as theterminals for the direct current output circuit. I

Since certain changes may be made in the above construction anddifferent embodiments of the invention could be made without departingfrom the scope thereof, it is intended that all matter contained in theabove description or shown in the accompanying drawing shall beinterpreted as illustrative and not in a limiting sense.
